IPC: G06K9/00
Filed: 1997-04-21
Abstract: PURPOSE: A biometric recognition system determines which features are most useful for identification purposes using a classification neural network. CONSTITUTION: The biometric recognition system involves two phase; creation (50) of a master pattern set of authorized users biometric indicia and authentication using a classification neural network. To create the master pattern set (50), an image of an authorized biometric user's indicia (51) is divided into a plurality of regions of interest or "features". The system determines which features are the most useful for identification purposes. Master patterns are then created from these master features, thus creating a master set. During authentication, a sample pattern set of a user to be authenticated is similarly created. A neural network is used to compare the sample pattern set with the master pattern set to determine whether the user should be
